If you look at that square again on the clip and freeze at 3.51
3. .9
8 .4
7
She was comleting the down row which needed 3 spaces filling in. Counting 1 to 9 the numbers needed were 2, 6 and 5.
Looking across you can see that there was already a 5 on the line so no go. then the 2 was on another line also the 6 was also used.. now watch and see from 3,51 on the clip how she placed that 5 and hopefully it will make sense then.
I can tell you that for someone like me that has always been useless at maths the sense of achievement is great
